Question

--- Why do you look so upset?
--- There are so many troublesome problems _________.

A．remaining to settle	B．remained settled
C．remaining to be settled	D．remained to be settled

Answer 1

C

试题分析：句意：---为什么你看上去这么伤心？---有这么多麻烦问题去处理。首先是考察非谓语动词,remaining…可以理解为“表示伴随”的定语，表示“仍旧还存在”修饰名词problems，
to be settled为“不定式的被动用法”表示“将要被解决”, 经常靠的类似题目还有It remains to be seen．故选C。
考点: 考查非谓语动词的用法。
